SPECIFICATION forming part of Letters Patent No. 354,506, dated December14, 1886.

Application filed May 6, 1686. Serial No. 201,306.

To @ZZ whom t may concern:

Be it known that I, BEEEND DoscHER, of Charleston, in the .county ofCharleston and State of South Carolina, have invented new and usefulImprovements in Swinging `Paddles for Vessels, of which the following isa full, clear, and exact description.

My invention relates to a system of propulsion for vessels, and has forits object to provide a simple, effective, and easily-controlledarrangement of swinging paddles at the sides of a vessel, whereby thevessel may be propelled forward or backward or turned short around toeither side without reversing the engine driving the main crank or powershaft, and with little noise, jar, or friction, and econonly of thedrivingpowerrlhe invention consists in certain novel featuresoi'construction and combinations of parts ofthe swinging paddles andtheir connections, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding .parts in all the figures.

Figure l is a side elevation, partly broken away, of a vessel fittedwith my improved'L swinging paddles, one of the paddle-beams also beingbroken away and in section. Fig. 2 is a plan view of one-half of thevessel and the paddles and their operating mechanism at that side. Fig.3 is a detail View of the paddie-adj listing mechanism at o ne side ofthe vessel as viewed from within the vessel. Fig. 4 is a cross-sectionalelevation of the vessel, showing the paddles at each side, and Figs. 5and 6 are detail views, to be hereinafter referred to.

To the top of the bulwarks or rails a a of the vessel A there are boltedlong boxes B B, two at each side, and fore and aft of the transversecenter of the vessel, or at about like distances fore and aft of themain power-shaft C, which has a crank, c, to which the engine-rod willbe connected to give motion to the paddles, as presently explained.

Each of the boxes B consists, preferably, of a bed-plate, I), and acap-plate, b', which are held together by thesarne bolts, b2, whichfasten the boxes to the vessel, and in each of the (No model.)

as may be to offer minimum resistance to their" passage through thelwater.

Each pair ofthe paddle arms D D are connected pivotally at g g with afore-and-aft-rang ling bar, G, and lthe bars G G of the paddle arms atthe saine side of the vessel are connected pivotall y at h h withthepitmen or rods H H, the other ends of which are connected to thewrist t' ofa cranlcarni, I, which is fixed to the outboard end of themain driving-shaft C, which shaft is journaled in boxes o c', iixed inthe sides of the vessel.

Each ofthe beams F has Vpivoted to it atj a paddle, J, which is free toswing fore and aft on the beam, except as it. may be prevented by one oftwo stop-pins, K L, which are fitted to slide vertically in the beam F,and so that the pin K may be lowered in front of the head of the paddleand the pin L may be lowered behind the head of the paddle.. Theopposing edges of the pins K L are provided with teeth 7c Z,respectively, which mesh into opposite teeth of a pinion, M, journaledin the beam F, directly above the paddle J, and whereby as either one ofthe pins K L is raised the other will be lowered, and vice versa.

The tops of the pins K L are connected to the opposite ends of a chain,N, which passes over a pulley, O, fixed to a shaft, P, journaled in thebox B. The loop of the chain is fastened to the periphery of the pulleyO byapin,

o, as clearly shown in Fig. 5 of the drawings.

To the inner end of each of the shafts P there is fixed a lever, B, andthe levers R R of the shafts P l? at the same sideof the vessel areconnected pivotall y, as s s, to the opposite ends IOD justing eitherthe port or the starboard paddle-pins KL, for controlling the movementsof the vessel, as presently described.

The pivotal connection of the blocks E with the ends of the paddle beamarms D allows the paddle-beams to swing toward and from the sides'of`the vessel, and to prevent the inner edges of the paddles J striking theship, shoulders e on the blocks E will act on shoulders d on the arms,as will be understood more clearly by comparing Figs. 4 and 6 of thedrawings.

The operation is as follows: As the crankshaft G is rotated forward orin direction of the arrow l in Fig. l, and when the levers R 1' at thestarboard and port sides of the vessel are thrown forward to turn theconnected wheels O and operate the chains N to lift the pins L, andatthe same time cause the pins K to be lowered in front of the paddles Jat both sides of the vessel, and as the paddle-beams F are swung foreand aft simultaneously by the rods G H and crank I, the paddles J willbe braced by thelowered pins Kas the beams move aft, whereby the vesselwill be driven forward, and on the reverse or forward stroke of thepaddles they will swing upward and feather 7 to the water and offerpractically little or no resistance to the forward movement of thepaddle-beams or the vessel. Should it be desired to back the vessel, thestarboard and port levers R r will be raised or swung over backward tothe positions indicated in dotted lines in Fig. l, whereby all thepaddle-pins K will be raised and the pins L will be lowered behind thepaddles J, so that the paddles will be effective on the forward strokeof the beams to move the vessel backward, and the paddles will featheron the back stroke of the beams, as will readily be understood. It isobvious that by lowering the paddle-pins K at one side of the vessel andthe pins L at the other side of the vessel, she may be turned sharplyaround to either side and almost within her own length. For instance,when the starboard-pins K and port-pins L are down, the vessel will turnto port,7 and when the starboard-pins L and port-pins K are down, thevessel will turn to starboard.

All the above-described movements of the vessel may be accomplishedsimply by adjusting the paddle-pins K L, and without reversing theengine driving the main shaft C; hence the vessels movements may beeasily controlled from the deck. Any suitable latches may be used tolock the levers R in their two eXtreme positions.

The pivot-pins hv h, connecting the barsG with the forward links, H, maybe removed to allow the forward arms,D D, their connectingbar G, and theattached paddle-beams F to be hauled up clear of the water by swingingthem forward on the pivots d d of the arms D D, and the aft paddle-beamsand connections may also be raised clear of the water when their pivotsh h are removed by swinging them vessel to proceed under sail alone whenit may be desired to do so.

In case of accident to either the starboard or port forward paddles ortheir connections, the entire forward system of paddles may bedisconnected from the driving-shaft and be hauled up at the side of thevessel, as above described, to allow the vessel to proceed under thepower of the aft paddles alone, and if the aft paddles be damaged theymay-be disconnected and raised and the vessel may proceed under thepower of the forward paddles alone.

Any suitable fender or guard may be let down at the sides of the vesselwhen docking her to prevent damage to the paddles and their connections.

This system of paddles may be applied to large vessels for ocean tradeor to river and canal boats, and when used to propel canalboats thebanks of the canalwill not be washed away, as there is very littlesplashing of water by the paddles. Y

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In swinging paddles for vessels, two pairs of arms, D D, one pairpivoted to bearings at each side of the vessel, a horizontal beam, F,provided with a paddle and connected to each pair of arms D D, a bar, G,connected pivotally to each pair of arms, a driving-shaft, O, oppositecranks I I thereon, and rods H, connecting the bars G with the cranks I,substantially as described, for the purposes set v forth.
